Cyrus Khambatta and Robby Barbaro are the co-creators of Mastering Diabetes, an online program and support network for people living with all forms of the disease: type 1, type 2, type 1.5, prediabetes, and gestational diabetes. And both have been living with type 1 diabetes, also known as insulin-dependent diabetes, for most of their lives. Type 1 can't be reversed or cured through diet and lifestyle, so they must take synthetic insulin in order to remain alive.
